Reaction Steps

To a -78° C. solution in THF (20 mL) of bis(4-(2-quinolylmethoxy)phenyl) ketone (992 mg, 2 mmol), prepared as in step 1, was added methylmagnesium bromide (3M solution in ethyl ether, 0.8 mL, 2.4 mmol) and the resulting mixture was stirred at room temperature for 12 hours. The mixture was then quenched with saturated aqueous ammonium chloride and extracted with ethyl acetate. The organic phase was washed with water and brine, dried over MgSO4, filtered, and concentrated in vacuo. The residue was purified by chromatography on silica gel (methylene chloride-ethyl acetate 4:1) to afford 920 mg (90%) of 1,1-bis(4-(2-quinolylmethoxy)phenyl)ethanol mp 129°-131° C.; 1H NMR (300 MHz, DMSO--d6) d 1.74 (s, 3H), 5.32 (s, 4H), 5.48 (s, 1H), 6.95 (d, 4H, J=9 Hz), 7.30 (d, 4H, J=9 Hz), 7.63 (m, 4H), 7.78 (m, 2H), 8.01 (m, 4H), 8.39 (d, 2H, J=8 Hz); MS (DCI--NH3) m/e 513 (M+H)+. Anal Calc'd. for C34H28N2O3 : C, 79.67; H, 5.51; N, 5.46. Found: C, 79.48; H, 5.62; N, 5.25.
